    Server Side Encryption: S3 <-> KMS to encrypt data

    SSE-S3: AWS S3 manages its own keys (rotated every month)

    Request Header - x-amz-server-side-encryption(AES256)

    SSE-KMS: Customer manages keys in KMS

    Request Headers - x-amz-server-side-encryption(aws:kms) and x-amz-serverside-encryption-aws-kms-key-id(ARN for key in KMS)

    SSE-C: Customer sends key with request (HTTPS mandatory)

    S3 performs encryption and decryption without storing the key

    Use HTTPS endpoints (secure data in transit)

    All AWS services (including S3) provides HTTPS endpoints

    Client Side Encryption: Client manages encryption

    Client sends encrypted data to AWS service

    AWS will not be aware of master key or data key

    AWS service stores data as is

    Use a client library (Amazon S3 Encryption Client)
